Really in the end I'm just pointing out that there's a good reason for our differences--partly due to training--and that I don't see this as a wall as much as an opportunity to gain a different perspective.-Fair enough. In medicine we are taught to have a list of 'differential diagoses', with the 'best' one first. But it is all based on the mental odds for it being true. We were also taught to write a 'present illness' illustrating the most probably diagnosis first. So you are right, I play the odds. And you are on the straight and narrow.
